[1] The main idea is to approximate the distribution of wealth with a small number of moments, e.g. it’s mean K, and specify a reduced-form law of motion for these moments.

http://perseus.iies.su.se/~tbroe/ WebOne just needs an extra fixed-point loop to update the equilibrium object, which can be coded in MATLAB. In Krusell and Smith (1998), the equilibrium objects are the aggregate state transition coefficients. The model can be solved within 100 lines of GDSGE code plus 100 lines of MATLAB code. We present the heterogeneous-beta version of the ...

WebBut solving for a law of motion that moves any initial distribution forward one period and that is consistent with the optimal policy function is a daunting task. In their 1998 paper, “Income and Wealth Heterogeneity in the Macroeconomy,” Krusell and Smith (KS from now on) proposed a way to work around this problem and include aggregate risk. WebKrusell and Smith (1998) show that in their heterogeneous-agent model, di ﬀer-ences between agents are small in the sense that the marginal propensity to save is very similar among agents. The marginal propensity is only di ﬀerentforthoseagents that are at or close to the borrowing constraint. There are, however, not many of
